پاسخ های شروع شده در اختلالات حرکتی عملکردی افزایش می یابد اما الگوی طبیعی دارند

This study shows enlarged, but normally patterned early startle responses in FMD. The high response frequency of the late responses found in these patients reflects a behavioral component. Hypersensitivity to external stimuli, often noted in FMD is supported by high response probabilities of both components of the auditory startle response.
